Cardiopulmonary exercise testing screening and pre-operative pulmonary rehabilitation reduce postoperative complications and improve fast-track recovery after lung cancer surgery: A study for 342 cases

BackgroundAn evaluation of cardiopulmonary exercise testing (CPET) screening and pre-operative pulmonary rehabilitation in reducing postoperative complications and improving fast-track recovery in high-risk patients who undergo resection for lung cancer. MethodsOf 342 potential lung cancer cases, 142 high-risk patients were finally divided into two groups: group R (n = 71) underwent an intensive pre-operative pulmonary rehabilitation program (PRP), followed by lobectomy; group S (n = 71) underwent only lobectomy with conventional management. Postoperative complications, average days in hospital, postoperative days in hospital, and cost were analyzed. ResultsThe 142 high-risk patients were screened by smoking history and CPET. Sixty-eight patients had bronchial hyperresponsiveness (BHR) and 47 patients had peak expiratory flow <250L/minute by CPET. The rate of postoperative total complications in group R (16.90%) was significantly lower than in group S (83.31%) (P = 0.00), as was the rate of postoperative pulmonary complications PPC: group R (12.81%) versusS (13.55%) (P = 0.009); the PPC in the left lung (17.9%) was higher than in the right lung (2.3%) (P = 0.00). The average days in hospital in group S was significantly higher than in group R (P = 0.03). There was no difference between groups in average hospital cost (P = 0.304). ConclusionPre-operative screening using CPET is conducive to identifying high-risk patients for lung resection. Pre-operative pulmonary rehabilitation is helpful to reduce postoperative complications and improve fast-track recovery.
